The Origin of Life - Abiogenesis - Dr. Jack Szostak
Ανέβηκε στις 8 Ιουν 2008
This has been CONFIRMED in Dr. Jack Szostak's LAB. 2009 Nobel Laurette in medicine for his work on telomerase.
It's
been 55 years since the Miller-Urey Experiment, and science has made
enormous progress on solving the origin of life. This video summarizes
one of the best leading models. Yes there are others. Science may never
know exactly how life DID start, but we will know many ways how life
COULD start. Don't be fooled by creationist arguments as even a minimal
understanding of biology and chemistry is enough to realize they have
no clue what they are talking about.
Note on how competition
works. Water will flow across a membrane to try to equalize the ion
concentration. If there is a lot of polymer in a vesicle it will be
surrounded by many ions, thus causing water to flow into the vesicle,
increasing the internal pressure and stretching the membrane. Fatty
acids are in equilibrium between the vesicle and solution. If 2 vesicles
are near one another they will gradually swap fatty acids. If one
membrane is under tension, the fatty acid "on rate" will be greater than
the "off rate" (move to a lower energy state by relaxing the pressure).
It will suck up fatty acids from solution. The other vesicle will still
give them off, but they will disappear (sucked up by neighbor) and not
return. Therefore, the vesicle with high internal pressure will grow and
the neighbor will shrink.
